Kamoer S3 Basic Sensor Module integrates temperature, humidity and liquid level detection. It can detect five liquid level signals, two temperature readings and one temperature and humidity reading with high precision at the same time. By connecting a Kamoer KICCI Intelligent Controller and using the Kamoer Aquarium Cloud app, the S3 sensor module allows you to monitor liquid level, temperature and humidity parameters at any time on your smart phone. When the level, temperature or humidity is abnormal, it can send an alarm to your smart phone in real time.
